About This Nutrition Study in West Hollywood

The goal of this Nutrition for Precision Health (NPH) powered by All of Us research study is to develop Artificial Intelligence/Machine Learning (AI/ML) algorithms that predict individual responses to diet patterns using rich multimodal data streams collected across multiple domains (e.g., behavior, social, environmental, clinical and molecular biomarkers). NPH includes a large phenotyping cohort (Module 1, N=8000) and two separate follow-up groups drawn from a subset of Module 1participants. One group (Module 2, N=1200) receives three distinct diets in a 14-day crossover sequence, with at least a 14-day washout period between diets, while living in their own homes. A second group (Module 3, N=150) receives the same three diets under full-time supervision in a residential research setting. We will train and test AI/ML models to predict 0-4 hour postprandial response curves for glucose, insulin, triglycerides, and GLP-1, to the standardized diet-specific meal test (DSMT) collected after each of the three different diets delivered in Module 2. Each diet functions as a controlled stimulus to reveal biological features (such as individual variables, patterns, or clusters of measurements) that best predict a person's response. The Module 2 DSMT response curves are the primary outcomes (dependent variables) for AI/ML algorithms that predict individual responses to diet patterns. As a secondary objective, NPH will evaluate the validity and acceptability of technology-based dietary assessment tools. The Automated Self-Administered 24-hour recall (ASA24), Automatic Ingestion Monitor-2 (AIM-2), and the mobile food record (mFR) will be evaluated in Modules 2 and 3, and the ASA24 food record and the image-assisted ASA24 recall will be evaluated only in Module 3. Total energy intake, macronutrient and dietary fiber intake data are the main outcomes for validity testing compared against measures of actual intake. Acceptability will be determined from feedback surveys.

Overall Inclusion -- Participants 18 years of age or older who have completed the primary All of Us consent process, Electronic Health Record consent process, have provided at least one All of Us biospecimen suitable for DNA sequencing, and have completed All of Us Participant Provided Information (PPI) Modules 1-3 (Basics, Overall Health, and Lifestyle); Speak English or Spanish; Able and willing to comply with study requirements and consent to participate.
Module 1 -- Must be willing and able to comply with Module 1 protocol; Must provide informed consent for Module 1.
Module 2 -- Must have completed Module 1; Must provide informed consent for Module 2; Must agree to comply with protocol over a period of approximately 10 to 12 weeks and up to six months. This includes consuming only the foods provided during periods of controlled feeding. Module 2 has three controlled feeding periods each lasting approximately two weeks with at least two weeks between feeding periods, and up to 6 months allowed for completion of the Module.
Module 3 -- Must have completed Module 1; Must provide informed consent for Module 3; Must agree to comply with protocol over a period of approximately 10 to 12 weeks and up to 6 months. This includes being domiciled three times, for two weeks each, and consuming only the foods provided during the domiciled periods. There is at least two weeks between domiciled periods, and up to 6 months allowed for completion of the Module.
